Musannaf Ibn Abi Shaybah

Hazrat Mak’hool says that I said to Hazrat Zuhri, “Do you not know that Hazrat Umar, Hazrat Ibn Mas’ood, and Hazrat Uthman bin Affan (may Allah be pleased with them) held the opinion until their deaths that the non-pregnancy of a slave-girl can be determined by one menstrual cycle? Whereas Hazrat Mu’awiyah (may Allah be pleased with him) held the opinion of waiting for two menstrual cycles.” Hazrat Zuhri said, “I will tell you of another companion, and he is Hazrat Ubadah bin Samit.”
